You can start this quest multiple times. Right now I have two active versions one with (150/375) the other with (150/500).
It seems like this is either two missions that are very similar or two copies of the same mission. It's very confusing none the less.
How to reproduce (If known.)
Start the quest. Log out, log back in, and you should be able to start a second copy of the same quest.
#### <- Spacer Of some sort,
Combat against the Tholians seems a little rough, they're quick, and that's a good thing. But combat seems like a kludge. It would be nice to have your officer follow them easier?? Not sure how to improve it.
